PRICE-SCALE.

SPECIFICATION forming part of Letters PatentNo. 557,064, dated March 24,1896.

Application filed April 19, 1895. Serial No. 546,331. (No model.)

To all whom t may concern:

Be it known that I, HARRY FISHER, of Neoga, in the county of Cumberlandand State of Illinois, have invented a new and Improved Computing-Scale,of which the following is a full, clear, and exact description.

The invention relates to computing-scales which give the value of anarticle at the given price per pound or other unit, and which price isvaried by the operator manipulating the scales.

The object of the present invention is to provide a new and improvedcomputin g-scale, which is simple and durable in construction, veryeiective in operation, reliable and always in proper balance.

The invention consists principally of' a Inovable point of connectionbetween the weighing-beam and the weighing-frame.

rlhe invention further consists of a movable weight for automaticallypreserving thebalance of the beam throughout all the changes of theconnection between the weighing-beam and the weighing-frame- Theinvention also consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claims.

Figure l is a front elevation of the improvement. Fig. 2 is a sectionalplan view of the same on the line 2 2 of Fig. l. Fig. 3 is an enlargedsectional front elevation, on the line 3 3 of Fig. 4, of the connectionbetween the weighing-beam and the frame-platform, and Fig. 4 is atransverse section of the same on the line 4 4 of Fig. 3.

The improved computing-scale is provided with the usual base A, on whichis erected a frame A supporting standards A2, formed in their upper endswith bearings A3 engaged by the knife-edges B2 of a rod B', forming partof the scale-beam B, supporting at one end a weight-carrier C, adaptedto receive the usual weights D.

On the beam B is fitted to slide a poise E adapted to indicate in theusual manner on thegraduation B3, so as to indicate the proper weight ofthe article to be weighed, it being understood that the weights Dindicate the 5o hundreds-weight and the poise E indicates theunits-weight up to 100.

On the rod Band on the side of the knifeedge B2 opposite to that onwhich the weights D are located, is fitted to slide a sleeve F, carryingknife-edges F projecting into loops G formed on arms G2, extendingupwardly from a second sleeve G mounted to slide longitudinally on themiddle portion of the frame Il, made U-shaped, and connected with thescale-platform arranged in the base A in the usual manner. The frame llhas its sidev arms Il fitted to slide in suitable bearings A4 and A5,fastened to the base-frame A, as plainly indicated in Fig. l.

The under side of the sleeve G is adapted to be engaged by a shoe I,preferably made semicircular, as is plainly indicated in Fig. 4, andsecured on the upper end of a stem I', fitted to slide vertically in abearing J formed at or near the middle of a carriage J, having itswheels J2 mounted to travel in slots K of guide-rails K, attached to thetop of the frame A. The stem Il carries at its lower end a spring I2,resting with its upper end on the under side of the carriage J and withits lower end on a collar 13, secured or formed near the lower end ofthe said stem I. The latter is provided near its upper end with a collarI", adapted to be seated on the top of the bearing J to limit thedownward movement of the stem 1/ and its sleeve I. A lever l5 ispivotally connected with the eXtreme lower end of the stem I', and thislever is fulcrumed at J on one end of the carriage J, as is plainlyillustrated in Figs. l and 3.

Now it will be seen that by the arrangement described the connectionbetween the scale-beam B and the frame H of the platform is made in sucha manner that the said connection can be shifted longitudinally on thebeam B by the operator manipulating the lever I5, so that a variationcan be had at any time between the weight of the scale-beam B and thepoint of connection between the scalebeam and the platform-frame H. Whenthe operator presses on the outer end of the lever 1:", he causes thestein I to slide upward, so as to Inove the shoe I in engagement withthe sleeve G, and as the said shoe I is pivotally connected by arms Lwith a second shoe L', adapted to engage the sleeve F, both sleeves Gand F are Inoved simultaneously, so that ICO the operator, uponoperating on the lever I5, causes the carriage J, and consequently thesleeves G and F, to travel forward or backward on the frame H and rod B,according to the push or pull given to the lever I5.

On the carriage J is formed a stud J '1, on which is mounted to turnloosely a disk N, adapted to roll on the top surface A of the base-frameA, so that as the said disk N turns the carriage J is moved forward orbackward in its bearings in the rails K. A pointer O which projects uponthe circular graduation N on the disk N is supported by an arm O/,attached to the carriage J.

Now it Will be seen that the graduation NQ which determines the priceper pound or other unit, is indicated on the fixed pointer O formingpart of the traveling carriage J, so that the operator on shifting thelatter can set the said disk on the pointer O to any price per pound orother unit of the article to be weighed. Y

In order to balance the weight of the connection between the beam B andthe frame II, I provide the following device: On the rod B, on theopposite side of the knife-ed ge B2 to that on which the sleeve F islocated, is iitted to slide a weight P connected at its lower end at oneside with a rope Q extending over a pulley R on the end of the beam Bnext to the weights D. The rope Q extends loosely through an opening inthe weight P to connect with a hook on one end of the sleeve F, and theother end of the latter is connected with a second rope Q passing over apulley R j ournaled on the other end of the beam B, as plainly indicatedin Fig. l. The rope Q connects with the weight P on that end opposite tothe one on which the rope Q is attached.

Now it will be seen that when the sleeve F is shifted, as previouslydescribed, by the operator manipulating the lever I5, then the weight Pwill move toward the knife-edge B2 at the time the sleeve F moves fromthe opposite side of the rod B toward the same knifeedge B2, and whenthe said sleeve moves outward away from said knife-edge B2 then theweight P likewise moves outward away from the said knife-edge. Thus theweight of the connection between the rod B and frame H is at all timescounterbalanced by the weight P moving in unison with the sleeve F onthe rod B.

The beam BS is provided in addition to its graduations with suitablefigures representing the prices of various goods, and it will be seenthat the price of any particular article will be automatically indicatedby the poise E and its position on the beam.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl.
